PROCESS OF MANUFACTURING GUNPOWDER.

No Drawing.

To all whom it mar concern:

Be it known t at 1, JOHN BUXBAUM, a citizen of the United States, residin at Georgetown, in the county of King and tate of Washington, have invented certain new and useful Improvements in Processes of Manufacturing Gunpowder, of which the following is a specification.

This invention relates to improvements in the process of manufacturing gun powder and has for its principal object to provide an improved gun powder.

Other objects will appear as my invention is more fully explained in the follow ing specification and pointed out in the appended claims.

Applicants process consists in first taking ordinary black gun powder; second, to saturate the powder with spirits'of camphor. In the second step in the operation it is important that enough camphor be added to make the mixture pasty and not to re- Third, allow the powder to thoroughly dry, After the powder is thoroughly dry it may be rammed into a cartridge or if a muzzle loading gun is used, it is rammed lightly in the usual' The? manner into the barrel of the gun. black gun powder if used may be prepared by mechanically mixing potassium nitrate, sulfur and charcoal in about the following Specification of Letters Patent.

'tivelv by weight, mechanically mixin Patented Feb. 4, 1919.

Application filed December 28, 1917. Serial No. 209,268.

proportions by weight: Potassium nitrate 75 per cent, sulfur 10 per cent. and carbon in the form of charcoal 15 per cent. The above percentages may be varied slightly without materially affecting the production. The various steps in grinding the ingredients of the powder, mixing the said ingredients and forming the powder into granules is so well known that the steps will not be taken up here.

I claim:

1. A process for the manufacturing of powder which embodies mechanically mixing black gun powder .with spirits of camphor into a plastic mass and thoroughly drying the plastic mass.

2. A process which comprises mixing potassium nitrate, carbon and sulfur in approximately 7570,1576 and 10% respecthe resultant powder with sullicient spirits of camphor to make a plasticmass, thoroughly dryin the mixture and forming it into granu es.

3. An explosive powder composed. of potassium nitrate, 75 per cent, carbon, 15 per cent. and sulfur 10 per cent. by weight and'sufiicient spirits of camphor to form a plastic mass.

In testimony whereof I atiix my signature.

JOHN BUXBAUM.
